To a/ZZ whom it may con/cern.-

Be 'it known that I, WILLIAM 1I. POTTER, of Bayonne, Hudson county, New Jersey, 'have invented an Improved Barrel-Hooping Machine, of which the following is a specification.

This invention relates to a machine of novel construct-ion by which thin metallic headhoops may be readily driven over the assembled staves without injuring the upper edge of the hoops.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of the machine on line :c oc, Fig. 2; Fig. 2 is a cross-section on line y y, Fig. 1, with arms a. omitted; Fig. 3, a top view of plate h2; Fig. 4, a perspective view of the head c; Fig. 5, a bottom view thereof; Fig. 6, a section on line 3 3, Fig. 5; Fig. 7, a perspective view of a modification of the head; Fig. 8, a bottom view, and Fig. 9 an end view thereof.

The letters ct a. d represent a series of arms or drivers arranged in a circle and pivoted to a common plate b by means of radial slotted ribs b4, caston such plate. The arms a may be swung outward and inward at their upper free ends, so as to release or grasp the barrelhoop. They may also be jointly lowered to draw the hoop over the staves. The mechanism for swinging the arms in and out and for raising and lowering the same is well known and forms no part of the present invention.

The present invention relates to the construction of the heads c, secured to the upper ends of the arms a, by which the barrel-hoop is grasped and drawn down. These heads are made in the form of an arc of a circle. They are provided with a shoulder or offset o', formed between an upper horizontal flange c2 and an outwardly-slanting vertical section e3. From this section there project downwardly one -or two beveled fingers c4. The heads c are of such width as to project latererally beyond the arms to which they are secured. A lug c5 projects rearwardly from head c, at right angles to fingers c4, and serves to attach the head to its arm. -In the construction shown in Fig. 1, and also in Figs. t and 6, a screw-bolt ct projects upwardly from the arm a and passes through a perforation in lug c5. A nut a2 holds the head c tightly upon the screw-bolt.`

In Figs. 7 and 9 the arm d has a hook- 'shaped end as engaging a notch c6 of the head is held in place by the bindingscrews c7 cs.

In use the arms d are first swung outward and the barrel A is placed centrally between them. The hoop B is putin place on the barrel and the arms areswung inward, so that the hoop is engaged by the shoulders c', Fig. 6-that is to say, the flange c2 rests upon the upper edge of the hoop to bear upon'the same, while the upright slanting pprtion c3 fits against the outer face of the hoop, following the bilge of the barrel.

outward in whole or in part under pressure. The beveled fingers c4 have for their object to guide the hoop into the shoulder or offset c. When the arms ct are swung inward, the flanges c2 form a complete circle that bears uniformly upon the entire hoop. The hoop being thus grasped by theheads, the arms a are lowered to pull the hoop over the staves, after which the arms are swung outward to release the hoop, when the operation is completed. By making the heads of such Width that they project laterally beyond the arms ce and by providing such laterally-projecting heads with the offsets c the hoops are not only grasped, but they are grasped with an equal tension at all points, so that they are not injured. l

In order to complete the description of the machine, the mechanism for vibrating and lowering the arms b Will now be briefly pointed out. The plate b has a tapped hub b2, engaged by a screwshaft d. This screw-shaft is revolved by means of bevelgear e e on shaft e', that may be shifted by a lever e2. Either of the wheels e may be made to engage a Wheel f, fast on shaft j", and carrying bevel-wheel f2. This wheel engages bevel-wheel d', fast on shaft CZ. As either of the wheels eis put into engagement with wheelf, the screw-shaft d is revolved either to the right or left, and t-hus the plate b, with its arms ce, is either raised or lowered. To guide the plate b in its vertical motion, it is provided with sockets b3, embracing fixed guide-rods g. In order to Thus the slanting Y section cE prevents the hoop from being bent c. The arm passes through a slot in lug c5 and swing the arms a outward and inward simultaneously, they are made to pass through slotted lugs h, pivoted to inclined arms h', that are in turn pivoted to a revolving plate 72,2. As either of the arms is grasped and pulled outward or inward, the plate h2 is revolved, thus causing a uniform motion of all the arms. One of the lugs 7L is open, so that the arm a engaged by it may be entirely lowered for the introduction and removalof the barrel.
